Does your hospital have an eye casualty unit you can contact? Otherwise contact your consultant as Ladygracie says. In the meantime try dissolving a little soda bicarbonate in warm, previously boiled water, and use it to clean along the lash line using cotton wool or cotton buds. This will reduce the crusting and make your eye more comfortable. If there’s a lot of crust you can lay a clean flannel or cotton wool soaked in warm water over your eyes for 5 or 10 minutes first to soften it..
Hope you get it sorted soon.
